Embodiment Construction

[0024] In order to make the above objects, features and advantages of the present disclosure more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] When the air conditioner is in cooling operation in summer, the low-temperature and low-pressure liquid refrigerant evaporates and absorbs heat in the internal unit evaporator to take out the indoor heat. The gaseous refrigerant then enters the condenser of the external unit. Under the forced convection heat exchange of the fan of the external unit, the high-temperature and high-pressure gaseous refrigerant in the condenser releases heat to the environment of the external unit, is cooled down, and condenses into a low-temperature and high-pressure liquid refrigerant; A throttling device (such as an expansion valve) throttling and decompressing turns it into a low-temperature and low-pressure liquid refrigerant. After the low-temper...

Abstract

The invention relates to the field of air conditioners, and provides a method of reducing an operating load of a compressor and an air conditioner. A refrigeration control method comprises the following steps of acquiring a condenser coiler temperature in a refrigerating condition; and reducing an air speed gear of an indoor fan in a condition that the acquired condenser coiler temperature is higher than a temperature threshold value corresponding to the existing air speed gear. The suction temperature and the suction pressure of the compressor are reduced by reducing the air speed gear of theindoor fan, so that the exhausting temperature and the exhausting pressure of the compressor are further reduced. The operating load of the compressor is reduced timely, so that shutdown caused by overload protection of the compressor in a high-temperature and high-load condition is avoided when the air conditioner refrigerates.

Description

technical field [0001] The present disclosure relates to the technical field of high temperature protection of air conditioners, in particular to a method for reducing the operating load of a compressor, and an air conditioner implementing the method. Background technique [0002] When the air conditioner works in a high-temperature environment in summer, the air conditioner will respond to the cooling demand of the user in the form of air output speed. The higher the cooling demand, the higher the air output speed, but in a high-temperature environment, the higher the air output speed, It means that the greater the workload of the air conditioner compressor, in a high-temperature environment, if the compressor's workload is too high, it will cause high-temperature overload protection, and triggering the high-temperature protection will cause the air conditioner to stop and fail to operate. [0003] When the air conditioner works under high load in summer, it is difficult to...
